Maybe... You might want to double check that you typed the equation properly in your original post. (Does your textbook really say

?)

are you people mathematicians or proffesors

I'm just some guy from Australia lol. I'm studying at university right now, but I'm definitely not a professor! I'm not even studying to become a mathematician. Though math is needed in a lot of different subjects.

Given a loan amount L, a term Y (in years) and a fixed monthly repayment P, I want to find (or at least approximate) the compound interest rate R. The loan is compounded monthly, once before each payment.

I've looked into geometric series, though it isn't too easy to solve for the ratio.

I'm using a computer to find the interest rate, so iterative methods are fine.

If you mean to say that zero is neither positive nor negative, you're absolutely correct. But '-0' isn't the same as saying 'zero is negative'!

To see why 0 is the same as -0 and +0, imagine +1, +2, and so on, as a line starting from zero, like this:

A negative number is the same as a positive number, except you reverse the line. It's Stays the same length and still starts at zero, but it's flipped. For example, -2 looks like this:

You can imagine "flipping the line" with numbers closer and closer to zero (shorter and shorter lines). But what happens when your line gets so short that it doesn't really have length? (You could say "0 length").

By that stage, you don't really have a line anymore. You have a point which represents zero:

Because it doesn't have any length "flipping" it doesn't change it, so +0 is the same as -0.

Ten is the the acceleration of Earth's gravity, 9.82 m/s/s. Some versions of this clock have it written as

so it equals 10 exactly.

Eleven is written in hexadecimal. In decimal, we have numbers 1 to 9, but in hexadecimal, as well as 1 to 9 there's 'a' to 'f' so you can keep counting: a equals ten, b equals eleven and so on. The zero at the front of '0b' doesn't make any difference here. It's just like writing the number three (in decimal) as 03.

Also, you can't test if TextWindow.Read() is equal to the variable 'test2' because you haven't set it to anything yet. But you already set the "test" variable to TextWindow.Read() on the second line of your program. What I think you meant to do is something like this:

Line by line, the program says this:1. Show the user "Testing" (print it out on the screen).2. Set the variable "test" to whatever the user types.3. Check if the "test" variable is equal to "Testing Reply" (without quotes). If it is, go to step 4, otherwise go to step 5.4. Show the user "This is text." (Without quotes, of course!) Then go to step 8.5. Check if the "test" variable is equal to "Testing Reply 2" (without quotes). If it is, go to step 6, otherwise go to step 7.6. Show the user "This is also text." Then go to step 8.7. Show the user "Sorry, this operation did not perform correctly." Then go to step 8.8. This is the "EndIf." It pretty much says "quit asking all these 'if' questions!"
